*your question doesn't really make sense... but if you mean what does the following distance when driving means... it is 2 seconds (at least) behind the car you are following. when the car in front of you passes a post etc count and see if it takes you at least 2 seconds to pass the same object at the same point of your car... hope that helps :)

You can maintain a proper following distance by?

The technique used for determining the proper following distance is the "3- second" rule.


On the expressway maintain a 3 to 4 second following distance if the road is slippery or what adjuster distance to?

6-8 second


How many second is recommended safe following distance in good conditions?

3


An advantage of keepinging a 3 -second following distance in city traffic is that you?

have time to react and avoid a collision.


Does the proper following distance vary with speed?

Yes, using either the 2-second rule or the 3-second rule means that as your driving speed increases, you leave more distance between you and the car ahead of you.


How do you measure following distance?

Following distance is typically measured in seconds. A common rule of thumb is the "3-second rule" where you should leave at least 3 seconds of following distance between your vehicle and the vehicle in front of you. To measure this, pick a stationary object on the side of the road, wait for the vehicle ahead of you to pass it, and then count how many seconds it takes for you to pass the same object.


What is following distance?

Following distance is the space between your vehicle and the vehicle in front of you while driving. Maintaining a safe following distance allows you more time to react to sudden stops or changes in traffic situations, helping to prevent rear-end collisions. The general rule is to keep at least a 3-second distance in good weather conditions, and more in adverse conditions.


On the expressway, maintain a 3-4 second following distance If the road is slippery or wet, adjust your distance to?

6-8 seconds


Average distance is 3 and average time is 2.40sec what is the average speed?

speed = distance/time = 3/2.4 = 1.25 distance units/second


Is recommended safe following distance in good condition?

3 Seconds


What is the 3 second plus rule in driving?

The 3 second rule (sometimes it's a 2 second rule) refers to the spacing a vehicle should maintain when following another vehicle, regardless of speed. The theory is that the faster the vehicles are traveling, the greater the margin of safety (spacing or distance) between the vehicles will be.


When implementing the 3-Second Rule you should select a fixed or stationary object in the road ahead?

Yes, in the context of driving, when applying the 3-Second Rule, you should choose a fixed or stationary object on the road ahead. This helps you maintain a safe following distance from the vehicle in front of you by ensuring that you have at least a 3-second gap between your vehicle and the one in front.
